Technical Guide Gauges and Sprinkler Gauges Industrial Gauges Ancillary Equipment
Introduction Pressure gauges in this catalogue are activated by a responsive metal element which deforms under the effect of the pressure being measured. The following British and European Standards form the basis of the design and manufacture of the Jet range Series of pressure gauges and of these guidelines. They should also be the source of reference for additional information: BS EN 837- : 998 Jet range has a wide selection of gauges and thermometers, which are used to monitor critical elements that must be controlled in order to achieve desired performance. This guide will allow you to select the most appropriate product to meet a variety of requirements. The Jet range encompasses: Safety The range of the pressure gauge should be selected such that the maximum working pressure does not exceed 75% of the full-scale value when measuring constant pressure, or 65% for fluctuating pressure. The criteria for the selection of a gauge are a function of four factors.. The pressure range (up to 25 bar, or, over 25 bar) 2. The dial size 3. Whether the gauge is Dry or liquid (eg glycerine) filled 4. The state of the material under pressure (as a liquid, or, as gas or steam) Storage Bourdon Tube Dimensions, Metrology, requirement and testing BS EN 837-2 : 998-50mm, 00mm, and 50mm diameters in a variety of pressure settings Pressure gauges should be kept in dry, clean conditions within a temperature range of -40 to +60 C and should be protected from impact damage. Installation 2 Selection and Installation recommendations for pressure gauges. BS EN 837-3 : 998 Diaphragm and Capsule - Dimensions, Metrology, requirement and testing - 00mm and 50mm diameter bi-metal thermometers - Clip on pipe thermometer - Electronic digital thermometer It is advisable to install the gauge with an isolating cock or valve that facilitates removal of the gauge for maintenance or replacement. On installation a leak tight seal should be achieved. If using sealing materials ensure these do not prevent the fluids entering the gauge. Gauges should be mounted vertically unless designed (and marked) otherwise. Gauges fitted with a blow out device must have at least 20mm clearance from any obstacle to permit the blow out device to operate correctly. Installation should take account of the ambient temperature conditions and should these affect the gauge adversely (eg cause the medium to freeze within the pressure element, then the gauge should be located remotely. A pressure gauge should not be installed in contact with fluids whose temperature is outside -30 to +60 C. Under these conditions a syphon should be installed or a suitably remote location selected, where the temperature conditions are more suitable. 3 The thermometers in this catalogue have circular dials and are actuated by a bimetal strip element, linked to the pointer. The following British and European Standard forms the basis of the design and manufacture of the Jet range series of thermometers and of their guidelines. The standard should also be the source of reference for additional information: Altitude and Sprinkler Gauges - 80mm combined altitude gauge and thermometer - Altitude gauges up to 40 metres - Sprinkler gauges are glycerine filled with two pressure options to choose from Safety The Jet range series of pipeline thermometers are supplied, as standard, with solid brass pockets with a process connection of 2" BSP. The pockets are produced as an interference fit on the brass stem to ensure a high degree of sensitivity. The thermometers should not be installed without these, or other pockets.

Installation will only measure the temperature experienced by the sensor probe. It is important, to achieve correct readings, that the probe is fully immersed into the flow of the pipeline or vessel. Correct nominal range and stem lengths must be selected before a thermometer is installed. Introduction
